Fix error message in Manage Users page

Description

I couldn't create a user in the Manage Users page.

[stop]Couldn't add user xxx - an unknown error occured.

1. It was because that user was locked, and I didn't see it. The error message
should say:
Couldn't add user xxx - User is locked, and you can unlock instead.

2. (Minor) - occured => occurred

3. Noticed that we can still delete users; that should just lock them instead
(and say so).
